Introduction
This project was created as a final project for Dr. Wood's CSC 471 Introduction to Computer Graphics class. I personally decided on this topic as the prompt was open-ended.The image analogies program takes three Bitmap images in, and will produce one output image. Similar to a word analogy, the program will be able to detect the relationship between two pictures and apply this to a third picture. Examples of this can be seen on the pictures page.
The program consists of two algorithms, one which executes in about 20-40 seconds. If this algorithm fails, the program will try to apply a second algorithm which takes about 30 minutes to apply (on a 800 x 600 picture).
Known problems
- The second algorithm is very lengthy, and has a very 40-70% chance of working perfectly
- There is no "fail case" for the second algorithm, so there is a small chance for unpredictable output
- Blurring is a known transformation that is not handled
- only 800 x 600 pictures have been tested
- Because GLUT flips the y-axis, the pictures are displayed upside down.
Future improvements
- Improve the performance of the second algorithm
- Improve functionality for different transformations
- Fix problems stated above
